[jira] [Resolved] (TAJO-49) Block-based compression of RowFile

     [ https://issues.apache.org/jira/browse/TAJO-49?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Hyunsik Choi resolved TAJO-49.
------------------------------
    Resolution: Won't Fix

It seems to be not relevant because we does not spend our time on row file and we do not have any plan for it. So, I close this issue Later, if it becomes necessary, we can reopen it.

> h3. Background
> RowFile is the row-oriented binary file format of Tajo. Currently, RowFile does not support compression. 
> h3. Proposal
> The goal of this proposal is to implement block-based compression of RowFile. Requirements are follows.
> * The compression type should be configurable via TableMeta. 
> * The block size also should be configurable via Configuration. 
> * LZO, BZip2, GZip should be supported. (I recommend utilizing Hadoop's CompressionInputStream/CompressionOutputStream)
